PPL Communication and Airspace Knowledge 2 — Questions and Answers
Question 1: What is the vertical limit of most Class B airspace above the surface?
- 10,000 feet MSL (Correct answer)
- 12,500 feet MSL
- 14,500 feet MSL
- 18,000 feet MSL
Correct answer: 10,000 feet MSL
Class B airspace typically extends from the surface up to 10,000 feet MSL.
Question 2: Before entering Class C airspace, a pilot must establish which of the following?
- Two-way radio communication with ATC (Correct answer)
- An IFR clearance
- Mode C transponder only, no radio
- Prior written authorization
Correct answer: Two-way radio communication with ATC
Class C entry requires establishing two-way radio communication with the controlling ATC facility.
Question 3: What color and style is used to depict Class D airspace boundaries on a sectional chart?
- Solid magenta line
- Dashed blue line (Correct answer)
- Solid blue line
- Dashed magenta line
Correct answer: Dashed blue line
Class D airspace is shown with a dashed blue line on sectional charts.
Question 4: What is the standard VFR communications frequency (Common Traffic Advisory Frequency) used at a non-towered airport when no other frequency is designated?
- 121.5 MHz
- 122.9 MHz
- 123.0 MHz
- The published CTAF/UNICOM (Correct answer)
Correct answer: The published CTAF/UNICOM
At non-towered airports pilots use the published CTAF, often the UNICOM frequency, for self-announce calls.
Question 5: A pilot experiencing radio failure while approaching a towered airport in VFR conditions should look for what signal from the tower to land?
- Steady green light (Correct answer)
- Flashing green light
- Steady red light
- Flashing white light
Correct answer: Steady green light
A steady green light gun signal clears an aircraft to land.
Question 6: What is the floor of Class E airspace in most areas away from airports where the transition area is charted with a magenta shaded band?
- Surface
- 700 feet AGL (Correct answer)
- 1,200 feet AGL
- 14,500 feet MSL
Correct answer: 700 feet AGL
The magenta shaded (faded) band indicates Class E begins at 700 feet AGL.
Question 7: The 100-knot maximum indicated airspeed restriction below 2,500 feet AGL within 4 NM of the primary airport applies to which airspace?
- Class B
- Class C
- Class D (Correct answer)
- Class E
Correct answer: Class D
Within Class D airspace, aircraft are limited to 200 knots, but the 100-knot rule referenced is a common speed consideration for certain operations; the 200-knot limit applies at or below 2,500 AGL within 4 NM.
